reference marker).
D-line The D-line (display line) is a horizontal line that can be positioned to
mark and read out an arbitrary level in the test diagram.
Ref
The hotkey Ref. R switches the reference marker on or off (use the ON/OFF key).
The reference marker is represented by the symbol
in the test diagram. The
marker position (abscissa) is defined in the input field Ref. Marker R. The marker
can be positioned to arbitrary time values. It is switched off in the default setting
(Off). The marker level is given by the measurement curve at the marker position.
The position of all markers can be varied using the rotary knob.
Remote control
No command, screen configuration only.
Rel
The Rel. 1 hotkey switches the delta marker 1 on or off (use the ON/OFF key).
The delta marker 1 is represented by the symbol
in the test diagram. The
marker position (abscissa) is defined in the input field Rel. Marker 1. The marker
can be positioned to arbitrary time values. If its position is outside the diagram area
it will be invisible and its coordinates will be “<abscissa_value> / - - -“. The marker
is switched off in the default setting (Off). The marker level is given by the meas-
urement curve at the marker position.
The toggle switch Rel 1 Config pops up when the hotkey is pressed for the second
time. It defines whether the position of delta marker 1 is measured and indicated in
absolute units (dBm) or relative to the reference marker.
Remote control
No command, screen configuration only.
Rel
The Rel. 2 hotkey switches the delta marker 2 on or off (use the ON/OFF key).
Functions and remote control are analogous to delta marker 1.
D-Line
The D-Line hotkey switches the D-line in the test diagram on or off.
The D-line is a horizontal, colored auxiliary line in the test diagram and is used for
marking a level value and for measuring level differences. The level (ordinate) is
determined in the input field D-Line and indicated on the D-line. The permissible
value range is the diagram area, the default setting is Off.
The switch D-Line Config. is opened by pressing D-Line twice and determines
whether the D-line level is expressed in absolute units (in dBm, setting absolute) or
relative to the RF Max. Level (in dB, setting relative).
Remote control
No command, screen configuration only.
Display
Marker
The Display/Marker softkey zooms or shifts the graphical display. It is selected by
pressing the Marker/Display softkey twice. If pressed once again, the selected Dis-
play/Marker softkey changes back to the Marker/Display softkey, see above.
